12.22 php-fpm慢执行日志
php网站运行慢，日志查看出错原因
vim /usr/local/php-fpm/etc/php-fpm.d/www.conf //加入如下内容
request_slowlog_timeout=1
slowlog = /usr/local/php-fpm/var/log/www-slow.log
配置nginx的虚拟主机test.com.conf,把unix:/tmp/php-fcgi.sock改为unix:/tpm/www.sock
重新加载nginx服务
vim /data/wwwroot/test.com/sleep.php //写入如下内容
<?php echo "test slow log" ;sleep(2);echo "done";?>
curl -x127.0.0.1:80 test.com/sleep.php -I
//如果报500错误，
// vi /usr/local/php-fpm/etc/php.ini
//改为display_errors =On
// /etc/init.d/php-fpm reload
cat /usr/local/php-fpm/var/log/www-slow.log
12.23 open_basedir
vim /usr/local/php-fpm/etc/php-fpm.d/aming.conf //[www]中加入如下内容
php_admin_value[open_basedir]=/data/wwwroot/aming.com:/tmp/
/etc/init.d/php-fpm restart
创建测试php脚本，进行测试
curl -x127.0.0.1:80 test.com/sleep.php -I
再次更改aming.conf，修改路径，再次测试
配置错误日志
vim /usr/local/php-fpm/etc/php.ini
改为display_errors =Off
error_log = /usr/local/php-fpm/var/log/php_errors.log
error_reporting =E_ALL
touch /usr/local/php-fpm/var/log/php_errors.log
chmod 777 /usr/local/php-fpm/var/log/php_errors.log
/etc/init.d/php-fpm restart
再次测试
curl -x127.0.0.1:80 test.com/sleep.php -I
查看错误日志
cat /usr/local/php-fpm/var/log/php_fpm/var/log/php_errors.log
